A. "colors": { 'brand-blue': '#1DA1F2' }
B. "colors": { brand-blue: #1DA1F2 }
C. "colors": { 'brand-blue': #1DA1F2 }
D. "colors": { brand-blue: "#1DA1F2" }

Solution

  1. Step 1: Check correct JSON syntax for Tailwind config

    Keys must be strings in quotes, and color values must be strings in quotes.

  2. Step 2: Identify the correct option

    "colors": { 'brand-blue': '#1DA1F2' } uses quotes correctly around both key and value, making it valid.

  3. Final Answer:

    "colors": { 'brand-blue': '#1DA1F2' } -> Option A

  4. Quick Check:

    Proper quotes around keys and values = "colors": { 'brand-blue': '#1DA1F2' } [OK]

  • Using unquoted keys in JSON
  • Using wrong quote types inconsistently
3. Given this Tailwind config snippet:
{
  theme: {
    extend: {
      colors: {
        'brand-green': '#10B981'
      }
    }
  }
}

B. A shade of green (#10B981)
C. Default Tailwind green

  • Assuming class won't work without import
  • Mixing up hex codes
4. You added a custom color brand-red in Tailwind config but bg-brand-red does not change the background color. What is the likely mistake?
medium
A. Using bg-brand-red instead of text-brand-red.
B. The hex code is missing the # symbol.
C. Tailwind does not support custom colors.
D. Forgetting to restart the development server after config change.

Solution

  1. Step 1: Understand Tailwind config changes

    Changes to Tailwind config require restarting the dev server to apply.

  2. Step 2: Identify the common mistake

    Not restarting means new colors won't load, so bg-brand-red won't work.

  3. Final Answer:

    Forgetting to restart the development server after config change. -> Option D

  4. Quick Check:

    Restart server after config edits = Forgetting to restart the development server after config change. [OK]

5. You want to create a consistent color system with Tailwind for a team. Which approach best helps keep colors consistent and easy to update?
hard

B. Use inline styles with hex codes everywhere in HTML.
C. Add colors directly in CSS files without Tailwind classes.
D. Let each developer pick their own colors for components.

Solution

  1. Step 1: Consider team consistency needs

    Using a shared config with named colors ensures everyone uses the same colors.

  2. Step 2: Compare options

    Inline styles and separate CSS files cause inconsistency and harder updates; letting developers pick freely causes mismatch.

  3. Final Answer:

    Define all custom colors in Tailwind config and use their names in classes. -> Option A
